Glassware

All items are 24/40 standard taper unless otherwise specified. Some items are not glassware, but are used in reaction setups.

Prices are from Sigma-Aldrich's catalogue. In reality these can be had much more cheaply on ebay.

Liebig condenser, 200mm ($55.10)

Allihn condenser, 200mm ($172.40)

3-neck 500mL round-bottom flask ($94.20)

500mL round-bottom flask ($30.70)

250mL round-bottom flask ($27.00)

100mL round-bottom flask ($23.50)

50mL round-bottom flask ($22.90)

2x50mL round-bottom flask with distiller arm (not standard taper)

Addition funnel, 125mL ($113.40)

Separating funnel, 100mL (not standard taper; use a 1-hole stopper for an adapter) (~$20 from American Science and Surplus)

Stillhead adapter ($68.10)

Vacuum adapter ($47.10)

Claisen adapter ($56.70)

0-360 degree thermometer

500mL beaker

250mL beaker

2x200mL beakers

40mL beaker

500mL one-arm Erlenmeyer flask (not standard taper)

Buchner funnel

100mL graduated cylinder

10mL graduated cylinder

10mL burette

Evaporating dish

Aquarium pump with hoses (attaches to condenser for cooling it down) (~$25 at any aquarium store)

Test tubes, various sizes, lots of them

2 ring stands with clamps

Hose clamps

Mortar and pestle

Reagents

1 gallon methanol

1 gallon phosphoric acid

1 gallon hydrochloric acid, 12M

~1lb potassium hydroxide

Calcium chloride, anhydrous (drying agent)

Magnesium sulfate, anhydrous (drying agent)

Things that are broken but could be fixed

A 500mL round-bottom longneck distillation flask with the distiller arm broken off. If someone has an acetylene torch, this could be repaired by fusing a glass tube onto it, or the hole could be sealed up and the flask used for a reflux reaction flask.

A Liebig condenser, not standard taper, with part of the stillhead end in several pieces. Again, fixable with a hot enough torch.

A vacuum aspirator with a bunch of pipe-fitting adapters. It works, but currently the adapters are on there really tight and I can't get them off. If someone has a plumber's wrench and a bench vise, this is easy to fix.

Workshops we could do

Distillation and drying. 99% ethanol is really expensive, but we can make it cheaply with everclear (or cheap vodka) and a little bit of work.

Liquid-liquid extraction and organic separation -- polar vs. non-polar solvents, how to use them

Column chromatography

Steam extraction from organic materials -- make your own essential oils and hydrosols

Acid/base extraction

Build a rotary evaporator

How to set up a reaction under reflux conditions

Fractional distillation

Build a fume hood

Things we should have on hand

There are many reagents which we should have in stock and which can be acquired easily from hardware stores or photography supply stores. Here are some, please add more:

Acetone (hardware store)

Xylene (hardware store)

Toluene (hardware store, though do they sell it in California?)

99% isopropyl alcohol (pharmacy)

Glacial acetic acid (photography supply)

Dichloromethane (hardware store)

Denatured alcohol (hardware store)

Naphtha (hardware store)

99% ethanol (can be purchased at places like The Science Shop in San Jose, but is very expensive; cheaper to make our own)

Silica gel (finer ground than the stuff that comes in packets, but we can grind it up in a mortar)

Calcium chloride (hardware store, "Damp-Rid")

Magnesium sulfate, anhydrous (pharmacy; buy Epsom salts and bake them in an oven to dehydrate, then put in a bag and crush into little chunks)
